humidity indicator sticker
Humidity indicator cards (HICs), which are mainly used for long-term storage and export packaging, indicate relative humidity (RH) inside a given barrier packaging. The indicator cards are impregnated with moisture sensitive spots that respond to various levels of humidity with a visible color change. The humidity indicator spots are reversible, and will change back to the original color when the humidity decreases.
Our standard humidity indicators offer detection across a wide range of humidity levels from 5% to 60% RH.
HICs can be used in the following domains, among others:
